java.lang.NoClassDefFoundError: Could not initialize class org.mockito.internal.util.MockUtil

Question

I want to use testng + powermock + spring to run test code,my jar version is:

powermock = 1.6.2
powermock-module-testng = 1.6.2 
mockito = 1.10.19
testng = 6.8.7
spring = 4.1.1.RELEASE
JDK = 1.8.0

And my test code as follows,and not extends AutoBaseTest, can run normal，AutoBaseTest contains @ContextConfiguration(locations={"/test/resources/applicationContext-test.xml"})

    @PrepareForTest({test.class}) 


  public class mockTest extends AutoBaseTest {

    @ObjectFactory
    public IObjectFactory getObjectFactory() {

        return new PowerMockObjectFactory();
    }


    @Test
    public final void test() throws Exception  {
        ......
    }
    }

the Error stack ：

Answer 1

It's a defect in Mockito with loading plugins when context class loader is different from which is used to load PowerMock and Mockito.

It could be fixed in Mockito 2, but as it mentioned in comments

Not sure we have the build infrastructure to backport the fix on 1.x

For Mockito 1, fix cannot be delivered, so I fixed in in PowerMock and fix will be include in next PowerMock release (PowerMock 1.6.5).
